Is c'a ore Dar 2 BY A TTORNEY Patented Jan. 6, 1931 UNITED'STATES PATENTOFFICE ISIDORE DANZIG, OF BROOKLYN, NEW YORK METHOD OF CONSTRUCTIHG ANDSTRAIGHTENING VEHICLE BODIES Application filed September 21, 1929.Serial No. 894,296.

This invention relates to motor vehicles and has more particularreference to a novel construction thereof, a method for suchconstruction, and-a method for repair due to bending of parts of saidconstruction during slight collisions and the like.

In congested city traflic and in small passages into private garages, itis extremely diflicult to escape denting the fenders on a car. The caris in continual danger and sooner or later denting is bound to occur.

0 owner of a new car prizes it highly and tries his best to keep it ingood condition. After several dents in the fenders and the body whichcannot be perfectly repaired, it has a moral effect upon the owner andhe tends to neglect the upkeep thereof. Accordingly, it is proposed toconstruct a car which willnot readily show dents and which can easily berepaired and in repaired condition be unrecognizable that any damage waspre viously sustained. g i

It is also proposed to construct a car which the owner may repairhimself as far as dents and slight bending of the fenders or the bodyiscQncerned. According to present day car construction it is necessaryto have a skilled body builder repair the car the repairing is notperfect easily recognize the places viously, people can repair bendingand dents and in repaired condition compete with the repairing of any ofthe present day cars by skilled body. builders.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to" the following descriptionand accompanying drawings, and to the appended claims inwhich thevarious novel features of the invention are more particularly set forth.I

In the accompanying drawing forming a material part of this disclosurend anyone can and even then of repair. Obthere is a great saving ifunskilled Fig. 1 is a perspective view of acar constructed according tothis arrangement.

Fig. 2 is an enlarged fragmentary sectional view taken on theline 2-2 ofFig. 1.

Fig. 3 is a fragmentary elevational view ipoking in the direction of theline 33 of Fig. 4 is a fragmentary enlarged sectional view as thoughtaken on the line H of Fig. 1 but disclosing another embodiment of theinvention.

The reference numeral 10 indicates generally a car of any design orconstruction and having a body 11, a hood 12, front fenders 13 withspare tire depressions 14, and rear fenders 15. The body and the fendershave a plurality of irregular indentations 16 upon its surfacessimulating hammered metal. The design may be uniform as illustrated in Fig. 3 or may be haphazard.

The method of constructing the car consists of forming the surfaces ofthe body and fenders irregular for simulating hammered metal, preferablywith each of the hammered blows disposed inwards or concaved. This 7method may be carried out by constructing the car with materialsinitially provided with the 1 irregularities for simulating the hammeredblows, which is the cheapest way of obtaining the construction, though,of 7 course, a car may be formed with the hammer blow-- structure afterit has been completely made. If made according to the former arrangement the sheets may be stamped 1n presses and thus form theirregularities.

A car constructed according to this invention may receive bends or dentsin its body or fender. The method of repair consists 1D first bendingout the dented or bent portions further than the correct positions andthen 35 with a hammer, striking the surfaces and gradually bending thesurfaces back Into their original positions. Thus the new concaveddepressions formed by the hammer blows in the method of reconstructioncomg mingle and mix with the hammer dents initially in the car and whenthe repair is co1 npleted it is practically impossible to recognize thatsuch repair has been done. If the design initially was uniform tracesmay be left of the repair work but the irregular surface of the carblends with the repairing surface in such a manner that recognition isimpossible to the eye of the ordinary observer.

The invention may be modified so that the car construction is composedwith its body and fenders having irregular surfaces simulating hammeredmetal with the hammer blows convexed or projecting outwards. When thusconstructed it is necessary to re pair the dents or bends in the car byhammering from the inside outwards or in other words so that the newhammer depressions correspond with those initially in the car.

InFig. 4, a modified form has been illus trated in which the hammerblows are concaved and convexed in the one car construction and arrangedfor ease in repairing. Preferably the edges of the fenders should beformed with concaved hammer blow depressions as indicated by referencenumeral 17 and the other parts of the fenders and the bodyshould beformed with convexed hammer blow portions 18. During the denting of thebody and the fender portions, the denting occurs in the great majorityof cases inwards and it is necessary to hammer the parts outwards forreturning them into their initial condition. For this reason theconvexed hammer blow portions on the body and the greater portions ofthe fenders are desirable. It is generally known that the edges of thefenders very often are drawn outwards in collisions and for this reasonthe concaved hammer blow depressed portions 17 are advantageous alongthe ed es in that the drawn out portions may be mmered inwards forforming the correct shape of the bent parts.

While I have shown and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is 1. In a vehicle construction,a body having a hood portion and fenders with an outer metallic surfaceformed irre ularly and simulating hammered metal so t at whenaccidentally deformed or bent may be hammered back into form so that therepair is unnoticeable, the hammer-blow irregularities on the edges ofthe fenders being concaved and the irregularities on the other portionsconvexed.
